If I'm not wrong, then I guess you are talking about recording "Stereo Mix" or loopback Output.

   In layman's terms, Recording Stereo Mix means recording sound from speaker output.

Here's how to do it:

  1. Install pavucontrol from Ubuntu Software Center.
  2. Install audacity from Ubuntu Software Center.
  3. Select pulse* as recording device in Audacity.
  4. Click Record Button.
  5. Open PulseAudio Volume Control (Search For PulseAudio Volume Control in Dash).
  6. Select Recording Tab.
  7. Now You Should see ALSA plug-in [audacity]. If you do not see ALSA plug-in [audacity], make sure you have clicked Record Button in audacity. You should be running recording in audacity while performing next step.

Pastikan

  • sampling rate 16000 Hz.
  • audio channels Mono.
  • PCM format as PCM unsigned 8-bit.
